Cell treatment device, cell treatment cartridge and body fluid treatment system

Abstract

A cell treatment device which allows cell dispersion liquid including cancer cells to pass therethrough to cause at least the cancer cells to be subjected to at least one of a physical action, a chemical action, and a biologically activating action, includes: a slit member having a first surface and a second surface and including a through hole having a slit shape penetrating from the first surface to the second surface and extending in one direction, the through hole having a tapered portion, wherein the width of a cross section of the tapered portion orthogonal in the one direction reduces from the first surface toward the second surface side, and is smaller than an average diameter of the cancer cells at an end on the second surfaces side, and the cell dispersion liquid is allowed to pass from the first surface side through the through hole to the second surface side.

Description

[0001]Japanese Patent Application No. 2009-078455 filed on Mar. 27, 2009, is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a cell treatment device, a cell treatment cartridge and a body fluid treatment system.[0004]2. Related Art[0005]In the related art, a method of administering an anti-cancer agent or a method of irradiating with a radioactive ray has been employed as a method of attacking cancer. Also, in recent years, as a further advanced method, a method of using an antibody / molecules target medicine, a method of using a cancer vaccine, and a method of using a gene manipulation are under development. Although these methods are intended to attack the cancer, a sufficient effect cannot necessarily be obtained regarding the metastasis of cancer.[0006]Death of human being due to cancer is caused by the metastasis of the cancer in many cases. In general, the metastasis of cancer is considered to occur in th...

AI Technical Summary

Benefits of technology

The device efficiently subjects cancer cells to desired actions, reducing metastasis risks and maintaining blood quality for administration, thereby improving treatment efficacy and patient quality of life.

Problems solved by technology

Although these methods are intended to attack the cancer, a sufficient effect cannot necessarily be obtained regarding the metastasis of cancer.

However, in the method of attacking cancer, attacking normal cells simultaneously cannot be avoided, and the normal cells are damaged.

Therefore, maintaining QOL (Quality Of Life) of patients high is difficult.

Therefore, the blood used for the diagnosis is difficult to use as blood preparation.

When such a method is applied for removing the circulating cancer cells from the blood, it means that the foreign substances are mixed to the blood and, when such the blood is administered, there is the danger such as remarkable lowering of the QOL or the risk of the patient's life.
